curs_insch(3X)                                                curs_insch(3X)

NAME         top

       insch,  winsch,  mvinsch, mvwinsch - insert a character before cursor
       in a curses window

SYNOPSIS         top

       #include <curses.h>

       int insch(chtype ch);
       int winsch(WINDOW *win, chtype ch);
       int mvinsch(int y, int x, chtype ch);
       int mvwinsch(WINDOW *win, int y, int x, chtype ch);

DESCRIPTION         top

       These routines insert the character ch before the character under the
       cursor.  All characters to the right of the cursor are moved one
       space to the right, with the possibility of the rightmost character
       on the line being lost.  The insertion operation does not change the
       cursor position.

RETURN VALUE         top

       All routines that return an integer return ERR upon failure and OK
       (SVr4 specifies only "an integer value other than ERR") upon
       successful completion, unless otherwise noted in the preceding
       routine descriptions.

       Functions with a “mv” prefix first perform a cursor movement using
       wmove, and return an error if the position is outside the window, or
       if the window pointer is null.

NOTES         top

       These routines do not necessarily imply use of a hardware insert
       character feature.

       Note that insch, mvinsch, and mvwinsch may be macros.

PORTABILITY         top

       These functions are described in the XSI Curses standard, Issue 4.

SEE ALSO         top


       Comparable functions in the wide-character (ncursesw) library are
       described in curs_ins_wch(3X).
